| Abstract | To investigate the effectiveness of a treat-and-extend regimen (TAE) of intravitreal ranibizumab injections (IVR) for macular edema (ME) due to branch retinal vein occlusion (BRVO). We retrospectively examined 35 eyes of 35 patients with ME due to BRVO who underwent TAE for 1 year. Patients whose treatment interval extended to 12 weeks were switched to a pro re nata regimen (PRN; TAE to PRN group), while TAE was continued for patients whose treatment interval was less than 12 weeks (continued TAE group). Changes in best-corrected visual acuity (BCVA), central retinal thickness (CRT), and predictive factors for inclusion in the TAE to PRN group were analyzed. BCVA and CRT both improved significantly at 1 year compared with baseline (p<0.001). Sixteen eyes (45.7%) were included in the TAE to PRN group, while 19 eyes (54.3%) were included in the continued TAE group. BCVA in the TAE to PRN group was significantly better than that in the continued TAE group at 1 year (p=0.047). BCVA at baseline and macular BRVO were significant predictive factors for inclusion in the TAE to PRN group. TAE was effective for improving BCVA and CRT. The TAE to PRN group showed significantly better prognosis. |

| Abstract | Few studies examined the relationship between social participation, physical activity and psychological distress in elderly people. Here we examined these relationships in apparently healthy elderly people. After exclusion of subjects who dropped out or did not meet enrollment criteria, the data of 86 subjects (apparently healthy elderly embers at a college health club; 25 males, 61 females) from July 20 to September 10, 2016 were used. We evaluated each subject’s psychological distress using the K6 questionnaire, social participation by a self-completed questionnaire, and physical activity level by a triaxial accelerometer (7 consecutive days). The K6 scores were significantly correlated with social participation in the total series and the women. The K6 scores of the subjects who had engaged in social participation (1.847±2.231) were significantly lower (better) than those of the subjects who had not (6.714±5.014). Both exercise limitation and social participation were significant predictors of the K6 scores. Our findings indicate that psychological distress in apparently healthy elderly people is not associated with physical activity, but is associated with social participation. Our results demonstrate that in healthy elderly people, participating in a social activity can help improve psychological distress. |

| Abstract | The gastrointestinal (GI) tract is the most frequently involved site of extranodal non-Hodgkin lymphomas, and diffuse large B-cell lymphoma (DLBCL) is the most common subtype occurring in the GI tract. TNFAIP3 (A20) genetic alterations were reported to be involved in DLBCL’s pathogenesis and a portion of GI-DLBCL cases harbor this alteration. However, the frequency and clinicopathological relations focusing on small and large intestinal DLBCL are unclear. Here, we examined A20 deletion and protein expression and analyzed the clinicopathological features of 52 cases of primary intestinal DLBCL. The most frequently involved site was the ileocecal region (75%), followed by small bowel (13.5%) and large intestine. Immunohistochemically, the ileocecal cases expressed BCL6 (p=0.027) and MUM1 (p=0.0001) significantly more frequently than the small intestinal cases. Six of 47 cases (13%) had A20 heterozygous deletion, whereas all 6 heterozygously deleted cases had detectable A20 protein expression. In summary, A20 abnormality was less prevalent among intestinal DLBCLs with some discordancy between gene deletion and protein expression. Although the A20 alteration status did not affect any clinicopathological characteristics in this series, further studies exploring alterations of A20 and other NF-κB components in primary intestinal DLBCL are needed. |

| Abstract | In patients with poliomyelitis, degenerative arthritis of the hip may be encountered in the paralytic or normal contralateral limb because of leg length discrepancy, pelvic obliquity, or severe deformities of the affected hip. Although total hip arthroplasty (THA) is one of the most common orthopedic procedures, there are few reports of THA in adult patients with residual poliomyelitis. From March 2001 to January 2011, 5 patients with residual poliomyelitis (6 hips) underwent THA using uncemented implants at our hospital. We retrospectively evaluated the Japanese Orthopedic Association (JOA) hip rating score, complications, and radiographs. All five patients’ follow-up information was available: 4.5 years minimum, 8.4 years average, range 4.5-15 years. Surgery was done at the same side of the paralytic limb in 2 hips and contralateral to the paralytic limb in four hips. All patients had pain relief and improvement in function; JOA hip rating score improved significantly from the mean of 45 preoperatively to 78 at the last follow-up (p=0.0313). There was no loosening or osteolysis in this series, and no cases of dislocation, infection or nerve palsy. These findings can contribute to decisions regarding treatment for arthritic hips in adults with residual poliomyelitis. |

| Abstract | Resistance training is effective against type 2 diabetes (T2DM), but the effect of resistance training on toe pinch force (TPF) is unknown. Here we investigated the effect of short-term toe resistance training on TPF in patients with T2DM, in a prospective, parallel-group, single-blind, randomized controlled trial. Twelve patients with T2DM who were hospitalized to improve glycemic control were enrolled. The patients were randomly allocated to the intervention (n=6) and control (n=6) groups. The intervention group performed traditional aerobic exercise and 4 newly developed toe-resistance training exercises. The control group performed aerobic exercise only. After 2 weeks of the exercise intervention program, we evaluated anthropometric parameters, clinical parameters, motor function, and muscle parameters in each patient. After the exercise intervention program, the TPF and toe muscle quality, isometric knee extension force, and knee muscle quality were significantly higher in the intervention group compared to the control group. Two weeks of toe-resistance training significantly increased the TPF in the T2DM patients. Toe resistance training is thus recommended in clinical practice for patients with T2DM. |

| Abstract | The number of permanent pacemaker implantations has been increasing due to the aging of populations worldwide and the increase in the numbers of patients with heart diseases. Commercially available mechanical pacemakers are very useful but still have some problems including short battery life, a risk of infection, the absence of physiological autonomic responsiveness, metal allergy, and electronic interference. A biological pacemaker may resolve these problems and regenerate the cardiac pacemaker. Cell-based therapy and gene therapy have been addressed with the goal of solving the challenges of biological pacemaker. However, the clinical application of a biological pacemaker has not yet been realized. Here we discuss the types of cells that can be used for a biological pacemaker and the problems that remain regarding the clinical applications of cell-based therapy. |

| Abstract | We treated a 72-year-old Japanese female with sustained high fever and overall body exhaustion. An infectious liver cyst and right lung pneumonia were suspected causes. Hepatic cystectomy and various antibiotics did not resolve symptoms. Pneumonia exacerbation and ascitic fluid retention, left lumbar spinal osteomyelitis, and peri-gastric lymph node abscess penetrating the stomach were observed. Mycobacterium avium was identified in sputum, ascites, vertebral body abscess puncture specimen, and pus mucus secretion in the stomach. We diagnosed a disseminated nontuberculous mycobacterial infection. She seemed immunocompetent, without signs of AIDS or hematological malignancy. Serum anti-IFN-γ autoantibodies tested positive and were suspected to be involved in the illness onset. |

| Abstract | The electrical activity of the diaphragm (EAdi) shows global diaphragmatic activation and power output from the central nervous system. We measured the EAdi as an indicator of breathing workload in a 40-year-old man suffering from severe acute respiratory distress syndrome (ARDS) secondary to influenza pneumonia in the process of weaning from extracorporeal membrane oxygenation (ECMO). Turning off the sweep gas flow immediately led to EAdi elevation, followed by hypoxia. The patient was successfully weaned from ECMO by reference to EAdi. This is the first case report to suggest that EAdi monitoring might be useful for ARDS patients during ECMO weaning. |

| Abstract | Internal limiting membrane (ILM) peeling is an important maneuver in vitrectomy for macular holes (MHs). A nitinol loop is a surgical instrument designed to create an edge on the ILM and peel the ILM safely and consistently. The effect of using a nitinol loop for ILM peeling on the retina is not clear. We report here on a case of an idiopathic full-thickness MH in an adult woman, in whom retinal damage was revealed after her ILM was peeled using a nitinol loop. |

| Abstract | Although spinal cord stimulation (SCS) is a useful treatment for chronic intractable pain, the optimal method of stimulation has not yet been established. In this prospective, crossover study, we compared the efficacy of using a constant current (CC) system with that of a constant voltage (CV) system for temporal SCS. Twenty patients were enrolled and divided into two groups. For 10 patients, a CV system was applied on Days 1-5, followed by the use of a CC system on Days 6-10. For the other 10 patients, a CC system was applied for the first five days, followed by a CV system for the subsequent five days. We evaluated the alteration of pain intensity using a visual analogue scale (VAS), the area of stimulation, the stability of effect, and patient satisfaction regarding treatment. The pain scores decreased significantly after the start of the SCS. There was no significant difference in the change in VAS between the two systems. The stimulation method used for temporal SCS did not affect the reduction of pain intensity. Patients felt a wider stimulation area by the CC system compared to the CV system. |

| Abstract | We investigated the anatomical features of the axillary nerve and its accompanying vessels with respect to the lateral wall of the greater tuberosity, focusing on the relationship between the neurovascular bundle and the proximal humeral locking plates. Magnetic resonance images of 30 Japanese patients’ shoulders were examined. Oblique sagittal images across the greater tuberosity and the neurovascular bundle, which contain the axillary nerve and posterior circumflex humeral artery and vein, were obtained. The distance between the superior aspect of the greater tuberosity and the superior and inferior borders of the neurovascular bundles was measured at the anterior, middle, and posterior edges of the greater tuberosity. The neurovascular bundle was 28.5-36.7 mm, 32.6-41.3 mm, and 38.1-47.5 mm distal to the superior aspect of the greater tuberosity at the anterior, middle, and posterior edges, respectively. We evaluated the relationship between the neurovascular bundle and 3 different locking plates, which were placed at the lateral aspect of the greater tuberosity. Only 3 or four locking screws at the most proximal part could be safely inserted without axillary nerve interference. |

| Abstract | Oral cancer is a very common disease in South and Southeast Asia. Betel quid (BQ)- chewing and tobaccosmoking habits are etiological factors for oral cancer patients in these regions. We conducted an oral cancer screening in BQ-chewing endemic rural areas in South Myanmar for the early detection of oral cancer in BQ-chewing and smoking individuals. We examined 105 subjects who were at high risk of oral cancer due to their oral habits (BQ users and/or smokers). Three carcinoma cases were detected, and there were 8 dysplasia cases. The carcinoma detection rate was 2.9%, and the carcinoma and precancerous lesion detection rate was 10.5%. In Myanmar, oral cancer screening has been conducted sporadically on a voluntary basis, and nationwide surveys have never been performed. There are also few reports of oral cancer screening for high-risk groups among the general population in Myanmar. Our present findings highlight the need for further screening and surveys. Education on betel quid chewing- and tobacco- related oral diseases and screening for the early detection of oral cancer are of the utmost importance in the control and prevention of oral cancer. |

| Abstract | We evaluated the feasibility of maintenance treatment using UFT (a combination of tegafur and uracil) after adjuvant platinum-based chemotherapy in patients with resected lung cancer. A prospective feasibility trial was conducted. Between 2010 and 2014, UFT was administered for 2 years sequentially after platinum-based adjuvant chemotherapy in 24 patients with resected Stage IIA-IIIA non-small cell lung cancer. The safety of UFT and the rate of treatment completion were then evaluated. The prior platinum-based chemotherapy regimens consisted of cisplatin+vinorelbine in 16 patients, carboplatin+paclitaxel in 5 and carboplatin+S-1 in one. During the subsequent UFT administration, a total of 3 patients required a dose reduction because of Grade 1 blood-stained sputum, Grade 2 numbness, and Grade 2 constipation, in one patient each. Eleven patients underwent the planned 2-year UFT administration, but 12 patients could not because of the recurrence of lung cancer in 5 patients, metachronous malignancy in one, and toxicities in 6. The completion rate for UFT administration was 64.7% (11/17). The most common type of toxicity was gastrointestinal toxicities. All of the toxicities were grade 1 or 2, and no severe toxicities were observed. UFT treatment after platinum-based chemotherapy was revealed to be feasible. |

| Abstract | (−)-Epigallocatechin-3-gallate (EGCG) has been shown to bind to several receptors including epidermal growth factor receptor (EGFR). EGFR tyrosine kinase inhibitors and anaplastic lymphoma kinase (ALK) inhibitors are effective for non-small cell lung cancers harboring activating EGFR mutations and ALK or c-ros oncogene 1 (ROS1) fusion genes, respectively. We investigated the effects of EGCG on EGFR- or fusion gene-driven lung cancer cells such as PC-9, RPC-9, H1975, H2228 and HCC78. The five cell lines had similar sensitivity to EGCG. Phosphorylated (p)EGFR, pAkt and pErk in PC-9, RPC-9 and H1975 cells were suppressed by EGCG (50 or 100 μM). EGCG also inhibited pALK in H2228, pROS1 in HCC78, and pErk and pAkt in both cell lines. All the xenograft tumors established using the 5 cell lines in EGCG-treated groups were significantly smaller than the tumors in the vehicle-treated groups. The numbers of tumor blood vessels of xenograft tissues in EGCG-treated mice were significantly lower than those in vehicle-treated mice. In conclusion, EGCG may be effective for EGFR-driven lung tumors irrespective of the presence of T790M, and for ALK or ROS1 fusion gene-driven lung tumors. |

| Abstract | Lavender essential oil (Lvn) has anti-inflammatory effects in an ovalbumin-sensitized murine model of asthma, and inhibits inflammatory cell infiltration into the lungs. The anti-inflammatory effects of Lvn on cell adhesion molecules are not clear. Here we evaluated the effects of Lvn and its main constituents, linalyl acetate (LA) and linalool (LO), on the expression of tumor necrosis factor-alpha (TNF-α)-induced cell adhesion molecules in murine brain endothelial bEnd.3 cells and human umbilical vein endothelial cells (HUVECs). The bEnd.3 cells were treated with Lvn, LA, or LO and subsequently stimulated with TNF-α. The mRNA expression levels of cell adhesion molecules were detected using RT-PCR. E-selectin and P-selectin protein and phosphorylated-NF-κB p65 were detected by western blotting. The effects of Lvn on HUVECs were measured by RT-PCR. In bEnd.3 cells, Lvn and LA suppressed TNF-α-induced E-selectin, P-selectin, vascular cell adhesion molecule-1, intercellular adhesion molecule-1, and phosphorylated-NF-κB p65 in the nucleus; LO did not suppress P-selectin or phosphorylated-NF-κB p65. Lvn inhibited TNF-α-induced E-selectin mRNA in HUVECs. These results indicate that Lvn and LA inhibit TNF-α-induced cell adhesion molecules in endothelial cells through the suppression of NF-κB activation. Consequently, Lvn or other essential oils including LA may be useful as alternative anti-inflammatory medicines. |

| Abstract | We examined postprandial body positions’ effects on gastrointestinal motility, the autonomic nervous system and subjective comfort, i.e., whether lowering the head after a meal is beneficial for gastrointestinal motility and the prevention of pressure ulcer. We examined 10 healthy subjects and compared 3 body positions: (1) Seated upright. (2) Lying on a bed with the head at 60° and knees up by 20° (60° position). (3) Identical to (2) until post-meal; the head was then lowered to 30° (60°-30° position). Gastrointestinal motility was assessed as gastrointestinal sounds measured by sound-editing software. Digital plethysmography assessed autonomic nerve function as heart rate variability. The pressure ulcer risk was estimated as subjective comfort/discomfort using a visual analog scale. Gastrointestinal sounds increased post-meal. The 60°-30° position showed the highest number of sounds and longest cumulative sound duration. Post-meal, sympathetic activation was suggested in the 60° position, whereas vagal activity was relatively preserved in the 60°-30° position. The 60°-30° position was the most comfortable, and the 60° position was least comfortable. Lowering the head after a meal is beneficial to augment gastrointestinal motility and decrease the pressure ulcer risk. The 60° head-up position increases the pressure ulcer risk. |

| Abstract | Several reports discussed colonoscopic surveillance after polypectomy and endoscopic mucosal resection (EMR) for colorectal polyps, but only a few reports focused on prognostic analyses, and none involved metachronous neoplasia after colorectal endoscopic submucosal dissection (ESD). We conducted the present study to assess the risk of adenoma recurrence requiring endoscopic treatment, and to establish appropriate post-ESD colonoscopic surveillance. We enrolled 116 patients who had undergone colorectal ESD at Okayama University Hospital between February 2008 and July 2014 and had been followed-up >12 months. We retrospectively analyzed clinicopathological features of 101 lesions from 101 patients. Metachronous adenomas were detected in 21 cases (20.8%). We divided the patients into 2 groups according to the occurrence of metachronous adenomas. Our comparison of clinicopathological characteristics between these groups showed that in the metachronous adenomas group the number of synchronous adenomas at index colonoscopy was high and the rate of laterally spreading tumor-nongranular (LST-NG) was higher. A multivariate analysis indicated that the number of synchronous adenomas was significantly associated with metachronous adenomas (HR: 2.54, 95%CI: 1.04-6.52, p<0.05). The colonoscopic surveillance planning after colorectal ESD should be more meticulous for patients with more synchronous adenomas. |

| Abstract | Early mobilization is advocated to prevent intensive care unit-acquired physical weakness, but the patient's workload and its changes in response to body position changes have not been established. We used indirect calorimetry to determine the energy expenditure (EE) in response to body position changes, and we assessed EE's correlation with respiratory parameters in healthy volunteers: 8 males and 8 females, mean age 23.4±1.3 years. The subjects started in the resting supine position followed by a 30° head-up position, a 60° head-up position, an upright sitting position, a standing position, and the resting supine position. EE was determined in real time by indirect calorimetry monitoring the subject’s respiratory rate, tidal volume (VT), and minute volume (MV). The highest values were observed immediately after the subjects transitioned from standing to supine, and this was significantly higher compared to the original supine position (1,450±285 vs. 2,004±519 kcal/day, p<0.01). Moderate correlations were observed between VT and EE (r=0.609, p<0.001) and between MV and EE (r=0.576, p<0.001). Increasing VT or MV indicates an increasing patient workload during mobilization. Monitoring these parameters may contribute to safe rehabilitation. Further studies should assess EE in critically ill patients. |

| Abstract | The receptor for advanced glycation end products (RAGE) is involved in inflammatory pathogenesis. It functions as a receptor to multiple ligands such as AGEs, HMGB1 and S100 proteins, activating multiple intracellular signaling pathways with each ligand binding. The molecular events by which ligand-activated RAGE controls diverse signaling are not well understood, but some progress was made recently. Accumulating evidence revealed that RAGE has multiple binding partners within the cytoplasm and on the plasma membrane. It was first pointed out in 2008 that RAGE’s cytoplasmic tail is able to recruit Diaphanous-1 (Dia-1), resulting in the acquisition of increased cellular motility through Rac1/Cdc42 activation. We also observed that within the cytosol, RAGE’s cytoplasmic tail behaves similarly to a Toll-like receptor (TLR4)-TIR domain, interacting with TIRAP and MyD88 adaptor molecules that in turn activate multiple downstream signals. Subsequent studies demonstrated the presence of an alternative adaptor molecule, DAP10, on the plasma membrane. The coupling of RAGE with DAP10 is critical for enhancing the RAGE-mediated survival signal. Interestingly, RAGE interaction on the membrane was not restricted to DAP10 alone. The chemotactic G-protein-coupled receptors (GPCRs) formyl peptide receptors1 and 2 (FPR1 and FPR2) also interacted with RAGE on the plasma membrane. Binding interaction between leukotriene B4 receptor 1 (BLT1) and RAGE was also demonstrated. All of the interactions affected the RAGE signal polarity. These findings indicate that functional interactions between RAGE and various molecules within the cytoplasmic area or on the membrane area coordinately regulate multiple ligand-mediated RAGE responses, leading to typical cellular phenotypes in several pathological settings. Here we review RAGE’s signaling diversity, to contribute to the understanding of the elaborate functions of RAGE in physiological and pathological contexts. |

| Abstract | Although recent retrospective studies suggested that the use of β-blockers appears to help improve the mortality rate and decrease the rate of exacerbation in chronic obstructive pulmonary disease (COPD) patients with heart failure, the effects of β-blockers on COPD patients without heart failure have not been established. Based on previous reports, we have launched a multicenter, prospective, single-arm phase II study to evaluate the preventive effect of the cardioselective β-blocker bisoprolol in COPD exacerbation, in Japanese individuals with moderate-to-severe COPD who do not have heart failure but do have hypertension requiring the use of medication. The primary endpoint is the rate of mild-to-severe COPD exacerbation. The results of this study will clarify whether bisoprolol can prevent exacerbation in COPD patients without heart failure. |
